Cisco CVOICE 8.0: Path Selection and Calling Privileges

Overview/Description
Path selection is one of the most important aspects of a well-designed VoIP system. High availability is desirable so that there is usually more than one path for a call to take to its final destination. Multiple paths provide several benefits, including redundancy in case of a link failure or insufficient resources on that link and a reduction in toll costs of a call. This course introduces the path selection strategies and methods to implement them. Calling privileges on Cisco IOS gateways are dial plan components that define the types of calls that a phone, or group of phones, is able to place. This course describes the concept of calling privileges and how they can be implemented on Cisco IOS gateways using class of restriction (COR).

Target Audience
The target audience for this course is established IT professionals with a solid, existing background in Cisco and networking technologies.
